In this embodiment, the execution main body may be the data transmission module 12 shown in fig. 1, and the phone end may be the phone 13 shown in fig. 1. As shown in fig. 1, when making a call, the phone 13 receives a control command of a user, converts the control command of the user into an AT control command, and then transmits the AT control command to the data transmission module 12 through the voice control channel, and the data transmission module 12 determines a recipient IP address corresponding to a called number included in the IP-based voice call request. Optionally, the called number is a number for dialing a VOIP phone, and is hereinafter referred to as an IP number.
For example, if the user initiates a command to dial an IP phone through the phone 13, and if the IP number dialed by the user is 12345, the IP number is first sent to the data transfer module 12, and the data transfer module 12 determines the IP address of the recipient of the IP phone dialed by the user corresponding to the IP number based on the IP number.

Step 203, transmitting the received voice data through a voice transmission channel.
As shown in fig. 1, after the telephone is connected, the telephone 13 uses the microphone to record the voice information of the user, forms digital voice data, and transmits the digital voice data to the data transmission module 12 through the voice transmission channel, and the data transmission module 12 transmits the digital voice data to the receiving party based on the IP network, thereby implementing the VOIP telephone service based on the data transmission module.
Optionally, the data transmission module 12 is further provided with a determining module 123, configured to determine whether the command is a command related to the VOIP service when the command is received, and if the command is a command related to the VOIP service, forward the command to the SIP unit 121, and the SIP unit 121 performs related processing, for example, the SIP unit dials a VOIP call, and when the SIP unit 121 receives a dial success indication, the command is analyzed into an AT command and sent to the phone 13. Phone 13 turns on the MIC and starts sending out the user's voice. And meanwhile, opening the spaker and starting to receive the voice of the user at the opposite end. After receiving the voice code stream of the opposite terminal, the RTP parses the code stream into a PCM format, sends the PCM format to the phone 13 through a PCM interface, and then plays sound by the phone 13.
The embodiment of the invention applies the provided voice data transmission method to the data transmission module, connects the data transmission module with the telephone end in a communication way, and then determines the IP address of a receiver corresponding to the called number included in the IP-based voice call request by responding to the IP-based voice call request sent by the telephone end; establishing a voice transmission channel based on a pre-acquired first operator IP address and a receiver IP address; and transmitting the received voice data through a voice transmission channel. Therefore, the voice service is realized on the data transmission module, so that the data transmission module can not only provide the data service, but also provide the voice service, the utilization rate of the data transmission module is improved, and the cost of the voice telephone is reduced.
Optionally, before responding to the IP-based voice call request sent by the phone terminal and determining the IP address of the receiver corresponding to the called number included in the IP-based voice call request, the method in the embodiment of the present invention further includes the following steps: acquiring an IP address of a first operator; and sending an IP data packet of the registration request, wherein the source address of the IP data packet is the IP address of the first operator, the destination address is the address of a pre-stored VOIP server, and the IP data packet also comprises registration information.
As shown in fig. 1, after being started, the data transmission module 12 first performs network connection with an operator server, the operator server returns a first operator IP address, and then the data transmission module 12 uses the first operator IP address as a source address and the VOIP server address pre-stored in the data transmission module 12 as a destination address to send registration information to the VOIP server corresponding to the VOIP server address for registration in the VOIP server. Optionally, the registration information includes: the IP number and IP address of the user initiating the registration. Meanwhile, the VOIP server can extract the IP number and the IP address in the registration information and establish the corresponding relation between the IP number and the IP address.
Optionally, the VOIP server address may be pre-stored in the data transmission module 12, or pre-stored in the main control module 11, and is issued to the data transmission module 12 by the main control module 11.
Optionally, determining, in response to the voice over IP call request sent by the phone terminal, a receiver IP address corresponding to a called number included in the voice over IP call request includes: and receiving a receiver IP address which is searched by the VOIP server and corresponds to the called number included in the IP-based voice call request in the pre-established corresponding relation between the called number and the receiver IP address. In this embodiment, the pre-established correspondence between the called number and the IP address of the receiving party is established by the VOIP server based on the registration information, for example, when the user registers in the VOIP server, the IP address of the first operator is used as the source address, the address of the VOIP server is used as the destination address, the registration information at least including the IP number and the IP address of the user is packaged into an IP data packet, and then the IP data packet is sent to the VOIP server through the data transmission module 12, and the VOIP server analyzes the IP data packet after receiving the IP data packet, extracts the IP number and the IP address in the registration information, and establishes the correspondence between the IP number and the IP address.
As shown in fig. 1, for example, if a user initiates a command to dial an IP phone through the phone 13, the IP number is first sent to the data transmission module 12 through the voice control channel, the data transmission module 12 sends the IP number to the VOIP server, so as to search an IP address corresponding to the IP number dialed by the user through the VOIP server according to the pre-established correspondence between the IP number and the IP address, and the searched IP address is an IP address used by a called user to be called by the user.
Optionally, on the basis of the foregoing embodiment, the main control module 11 may further obtain an IP address of a second operator in a manner of VOIP APN dialing, where the IP address of the second operator is used to provide a data service for the main control module. The main control module 11 and the number transmission module 12 may respectively obtain the IP address of the second operator and the IP address of the first operator in a dual APN dialing manner. The first operator IP address and the second operator IP address are used to provide voice services and data services, respectively.
Example two
Fig. 3 is a flowchart of a voice data transmission method according to another embodiment of the present invention. Fig. 4 is a diagram of another application scenario applicable to the embodiment of the present invention. Fig. 4 is the same as the structure in fig. 1, and may refer to the description of the hardware structure in fig. 1, except that the data flow direction is different (the data flow direction may refer to the dashed line shown in fig. 4). As shown in fig. 3 and fig. 4, on the basis of the foregoing embodiments, the voice data transmission method provided in this embodiment specifically includes the following steps:
step 301, packaging the voice call request based on IP sent by the phone terminal and the pre-allocated private network IP address into a first voice call request and sending the first voice call request to the main control module, so that the main control module converts the private network IP address into a first operator IP address, and packaging the voice call request based on IP and the first operator IP address into a second voice call request and returning the second voice call request to the data transmission module.
In this embodiment, the main control module 11 obtains the first operator IP address from the operator server by means of APN dialing, and the data transfer module 12 cannot obtain the first operator IP address, so the main control module 11 may allocate a private network IP address to the data transfer module 12, and next hops of the data transfer module 12, the SIP unit, and the RTP unit are all set as the main control module 11, so uplink IP data packets of the data transfer module 12, the SIP unit, and the RTP unit all need to pass through the main control module 11. Similarly, the downlink IP data packet needs to first pass through the main control module 11 and then reach the data transmission module 12.
As shown in fig. 4, for example, the user initiates a command to place an IP call through telephone set 13, the command for dialing the IP phone will first reach the data transmission module 12, and the data transmission module 12 will use the private IP address allocated to the data transmission module 12 by the main control module 11 as the source address, the address of the VOIP server as the destination address, the IP data packet (the first voice call request) is packaged together with the command for making the IP call and sent to the main control module 11, and after the main control module 11 receives the IP data packet (the first voice call request), the private IP Address in the IP data packet (first voice call request) is converted into the IP Address of the first operator through Network Address Translation (NAT), the first carrier IP address is then used as the source address, the address of the VOIP server is used as the destination address, and the IP data packet (second voice call request) is packaged together with the IP call dialing command and sent to the data transmission module 12.
Step 302, receiving the second voice call request and sending the second voice call request to the VOIP server, so as to determine, by the VOIP server, a recipient IP address corresponding to the called number included in the IP-based voice call request.
Optionally, after receiving the second voice call request and sending the second voice call request to the VOIP server, the method further includes: and receiving a first response message sent by the master control module, wherein the first response message is obtained by the master control module performing address conversion on a destination address based on a second response message of the second voice call request returned by the VOIP server.
Optionally, the first response message is obtained by the host control module performing address translation based on the response message of the second voice call request returned by the VOIP server, which means that the first response message is obtained by the host control module translating the first operator address in the second response message into a private network IP address.
Please refer to the above example, after receiving the IP data packet (the second voice call request) with the source address modified by the main control module 11, the data transmission module 12 sends the IP data packet to the wireless network, and finally sends the IP data packet to the VOIP server through the wireless network, after receiving the second voice call request, the VOIP server searches for a corresponding IP address in the pre-established correspondence between the IP number and the IP address according to the called number carried in the IP data packet, and uses the IP address of the VOIP server as the source address, the IP address of the first operator as the destination address, and packs the IP address together with the searched IP address into an IP data packet and returns the IP data packet to the main control module 11.
And step 303, establishing a voice transmission channel based on the pre-acquired first operator IP address and the receiver IP address.
Please refer to the above example, after receiving the IP data packet sent by the VOIP server, the main control module 11 performs NAT conversion on the destination address of the IP data packet, converts the destination address into a private IP address, and then packages the private IP address as the destination address and the IP address of the VOIP server as the source address together with the found IP address into an IP data packet to send to the data transmission module 12. The data transmission module 12 receives and analyzes the IP data packet of the VOIP server to obtain the IP address of the receiving party, and establishes a data transmission channel with the receiving party by the SIP unit.
And step 304, transmitting the received voice data through a voice transmission channel.
Optionally, transmitting the received voice data through the voice transmission channel includes: sending the received voice data and a pre-allocated private network IP address to a main control module so that the main control module converts the private network IP address into the first operator IP address and returns the voice data and the first operator IP address to the data transmission module; taking the IP address of the first operator as a source address and the IP address of a VOIP receiver as a destination address; and transmitting the source address, the destination address and the voice data through the voice transmission channel.
In this embodiment, different from the first embodiment, when the voice data is transmitted, the network address needs to be converted through the main control module 11. Specifically, after receiving voice data sent by a user through a microphone of the phone, the data transmission module 12 packages and sends a private network IP address, the voice data and an IP address of the VOIP server to the main control module 11, the main control module 11 performs NAT conversion on the private network IP address into an IP address of a first operator, then packages and returns the IP address of the first operator, the voice data and the IP address of the VOIP server to the data transmission module 12, and then the data transmission module 12 transmits the data to a wireless network through a voice transmission channel and finally reaches a receiving party.
Similarly, after receiving the voice data sent by the receiving party, the user also first arrives at the main control module 11, then performs NAT conversion by the main control module 11, and then sends the voice data to the data transmission module 12, and then feeds the voice data back to the telephone terminal after being analyzed by the data transmission module 12.
The voice call request based on the IP sent by the phone terminal and the pre-allocated private network IP address are packaged into a first voice call request and sent to the main control module, so that the main control module converts the private network IP address into a first operator IP address, and packages the voice call request based on the IP and the first operator IP address into a second voice call request and returns the second voice call request to the data transmission module; and receiving a second voice call request and sending the second voice call request to a VOIP server so as to determine a receiver IP address corresponding to a called number included in the IP-based voice call request through the VOIP server. Therefore, the voice service is realized on the data transmission module, so that the data transmission module can not only provide the data service, but also provide the voice service, the utilization rate of the data transmission module is improved, and the cost of the voice telephone is reduced.
EXAMPLE III
Fig. 5 is a flowchart of a voice data transmission method according to another embodiment of the present invention. On the basis of the foregoing embodiment, the voice data transmission method provided in this embodiment specifically includes the following steps:
and step 501, acquiring the IP address of the first operator.

Step 503, converting the private network IP address in the first voice call request into the first operator IP address, and forming a second voice call request to be returned to the data transmission module, so that the data transmission module sends the second voice call request to the VOIP server corresponding to the IP address of the VOIP server.
In this embodiment, since the source address in the message sent by the data transmission module 12 is the private IP address allocated by the main control module to the data transmission module, and cannot directly communicate with the outside, the message sent by the data transmission module 12 needs to undergo NAT conversion on the source address through the main control module 11, and then communicates with the outside after being converted into the first operator address. For an external IP data packet received by the main control module 11, it is also necessary to perform NAT conversion on the destination address through the main control module 11, and after converting the destination address into the first operator address, the destination address is sent to the data transmission module 12.
